Organic Reactions Worksheet ANSWERS

  1. a K2Cr2O7 B i. displayed formula with –CHO (aldehyde);

displayed formula with –COOH group

ii Gives aldehyde after mild heat and distilling immediately; gives carboxylic acid after refluxing with excess oxidising agent.

iii aldehydes; then carboxylic acids

iv e.g. CH3CH2OH + [O] → CH3CHO + H2O e.g. CH3CH2OH + 2[O] → CH3COOH + H2O

c i displayed formula with >C=O group (ketone)

ii ketones

iii e.g. CH3CHOHCH3 + [O] → CH3COCH3 + H2O
